Sectoral factsheets for climate change

United Nations 2 years ago

The world is warming faster than at any point in recorded history. This is radically changing the Earth’s climate and releasing a wave of extreme weather, including wildfires, hurricanes, floods and droughts. But humanity can still avoid the worst impacts of this climate crisis. To do that, the Earth’s temperature must be prevented from rising to more than 1.5 °C above pre-industrial levels. The only way to avoid catastrophic climate change is to rapidly slash our emissions of planet-warming greenhouse gases, including carbon dioxide. These emissions, which come largely from burning fossil fuels, have continued to rise in recent decades despite a raft of international accords, including the Paris Agreement. To keep the 1.5°C temperature target alive, the world needs to cut 2030 emissions by 42 per cent. This must be done in tandem with climate adaptation. National Adaptation Plans in particular, are crucial for ensuring climate resilience is built into each of the sectors. By 2025, every country must commit to new National Determined Contributions (NDCs), these NDCs must cover all emissions and sectors. Global ambition in the next round of NDCs must bring global greenhouse gas emissions in 2035 to levels consistent with the 1.5°C pathway. Explore these factsheets to learn how.

This news batch contains no substantive sustainable construction development: no major breakthrough in low carbon construction materials, no new whole life carbon assessment mandate, no building-code reform, no retrofit programme, no procurement shift, no BREEAM v7 update and no significant project case study advancing net zero carbon buildings.

The relevant signal is indirect but important. COP31 debate over the timing of the next IPCC reports could shape the 2028 global stocktake, influencing national policy on whole life carbon, embodied carbon, lifecycle assessment, retrofit finance, planning standards and the carbon footprint of construction. Warnings over El Niño costs and weakening natural carbon sinks strengthen the case for climate-resilient, energy-efficient buildings, low carbon design and faster cuts to operational emissions and embodied carbon in materials.

For the construction sector, the absence is commercially revealing. Environmental sustainability in construction remains too often downstream of climate diplomacy rather than central to it, despite the built environment’s major role in energy demand, resource use and emissions. Sustainable building design, eco-design for buildings, circular economy in construction, sustainable material specification and building lifecycle performance need clearer policy treatment if governments are serious about decarbonising the built environment.

The practical agenda remains unchanged: net zero whole life carbon, credible environmental product declarations (EPDs), low embodied carbon materials, life cycle cost analysis, end-of-life reuse in construction, resource efficiency in construction and circular construction strategies must move from specialist practice into mainstream procurement. Without that shift, green construction and eco-friendly construction risk remaining policy aspirations rather than measurable progress in sustainable building practices.
